GASOLINE RESERVE.

Application filed Zanuary This invention relates generally to means forproviding a reserve capacity 111 a liquid holding tank.

7 with IL is saown as appned LO the -uei tank of HHYJIHOIH0UVB vehiclein which means are provided for retainin a quantity of fuel within thetank to provide a reserve capacity. In the particular arrangementembodied in the invention, in normal opertion the fuel tank connot beentirely drained. VJhen it has been drained to ti 'normal lowest level,the op ator may thereafter change the setting of his reserve fuel valveand thereaft r draw upon his reserve capacity. It is one of the objectsof the invention to provide means for carrying out Another object is toprovide in a valve itself a construction whereby any ordinary tankwithout any reconstruction may be arranged to have a leserve fuelcapacity. Another object is to provide such'a'valve which can beinserted readily in connection with a standard fuel tank and fuel supplysystem without the necessity of remachining or altering any of the usualparts already-in place. Other objects will appear from time to timethroughout the specification and claim.

My invention is illustrated more or less diagrammatically in theaccompanying drawing; wherein Figure 1 is a fragmentary side elevationof an automobile with parts in section;

Figure 2 is a side elevation of a valve showing the operating wheel;

Figure 3 is a vertical cross section showing the valve;

Figure 4 is a transverse section taken on line 3-3 of Figure 3.

Like parts are designated by like characters throughout.

The automobile is indicated generally at A. B is a fuel tank. C is anengine. I)

is a sediment pocket or bulb through which the fuel flows and it iscontrolled by a valve which is indicated at E D is a per ion of afuelline running to the carburetor of the engine. These details will not befurther illustrated as they form no particular part of the presentinvention. Y

My invention is not limited to an association with them. lVIy inventionis indicated in Figure 1 generally at E. As shown in greater detail inlater figures, it is formed of a generally straight tubular body havingat one end an inlet opening In the form illustrated here- S, 1926.Serial No. 80,108.

E It is provided at its other end with an I outlet opening E* which isinteriorly threaded as at E Connected with the tubular part E betweenits ends and communicating with the tubular passage therethrough, iswith a vertically extending generally tubular body E which is threadedexteriorly at its open upper end as at E I Extending centrally of thisvertically fdis; posed tubular body is a partition wall which stopsshort of the top ofth'e member E and thus extends downward and acrossthe tubular member E being provided with a generally cylindricalenlargement, F which has an inlet opening FF and an outlet opening Fsuch openings being inclined with the tubular opening or passage throughthe part E v 'VVithin the bore of the cylindrical enlargement F isavalve G which has through ti'on to'register with openings F and F.

This valve is provided with a reduced extension G on which is fastened alimiting member G and on which is also fastened a controlling andoperating wheel G. This wheel may have an indicator such as the arrow VG is a packing about the valve reduced portion G Gr isa packingretaining gland by means of which the valve is held in position, thepacking iscompressed anddisplacernent "ofthe parts and leakage of thefluid within the valve isprevented,

H is a pressure escape tube, fastened'to the upper end E of the part Eand held thereto by means of a nut H. H H are spacing washers. The tubeH is preferably provided with a downwardly bent upper end H I is aprojection connected to the tubular portion E of the valve. As shown inFigure 2 it is generally horizontal. I is a similar projection and'isgenerally vertical. Then the member G is in contact with the projectionI the emergency supply valve is closed and as shown in Figure 2 thearrow points upward. WVhen the member Gr is in contact with theprojection I the arrow points horizontally and the emergency supplyconnection is open and free to be drawn upon. n

The attachment which I have invented and which has been described has,besides advantages that have been pointed out, these also: the articleis very simple construc tion and hence may be very easily and cheap- 1manufactured and besides it may be easily 0 eaned of sediment or othermaterial that might tend to form a stoppage in the line by removing thecasting E and the several fluid passages through it including others inthe valve and its seat are exposed, and are relatively close to anddirectly in line with the several open ends of the casting, permit tingthe interior passages to be readily wiped This can be done without.

out and cleaned. removing any part of the connection, it only beingnecessary that the several couplings, as I term E E and E be separated.

Although I have shown an operative device, still itwill be obvious thatmany changes might be made insize, Shape and arrangement of partswithout departing materially frointhe spirit of my invention: and Iwish, therefore, that my showing be taken as in a sense diagrammatic.

The use and operation of my invention are as follows: 7

When it is desired to insert my valve in the fuel line of an automobile,the normal fuel connection to the tank is removed and my valve isscrewed directly into the fuel outlet of the tank, the part E beingscrewed into this outlet. The normal fuel line connection is'thensecured to the part of my valve, and fuel may be taken to the fuel lineas usual.

In normal working conditions the va ve will be adjusted as shown inFigures 2, 3, and 4 so that the fuel drawn out of the valve and throughthe fuel system must pass through thetop of the partition F.

The pressure escape tube H is provided to prevent any siphoning actionwhich might be set up and cause the tank to empty. When the fuel hasbeen drawn down to the point substantially equal with the top of thepartition F, further fuel withdrawal will stop. The driver may thenoperate the valve to permit fuel to pass through the opening of thepartitionthat is through the openings F F and the registering passage Gand the fuel may then be drawn down to its lower level. Thus ,a reservesupply is provided in the tank without reconstruction or alteration ofany of the parts of the ordinary fuel supply system.

I claim:

A reserve supply attachment for fuel tanks consisting of a castinghaving a straight tubular portion with openends adapting it to beattached to the fuel line, and having also an intermediate verticaltubular portion disposed at right angles to the first-namedtubularrportion and connecting therewith intermediate its ends, apartition in the said intermediate tubular portion terminating short ofthe open end thereof, and forming a barrier to the fluid passage throughthe horizontal tubular portion, the portion of the partition in thehorizontal tubular part of the attachment beingformed into a hollowcylindrical enlar ement shaped to constitute a valve seat,suchenlargement having openings which are respectively beside the open endsof the horizontal portion of the attachment, a valve seated in saidenlargement provided with a cross opening adapted to register with theopenings through the valve seat and put them in communication with eachother or to intercept such communication aceordingly as the valve isadjusted and a vent tube connected with the open end of the verticaltubular part of the attachment the several passages through the castingand the valve being disposed opposite the open ends of the tubular partsfor ready cleaning when the attachment disconnected.
